Strange Memory Corruption Problem with Core2Duo E6700, P965 Chipset MB and >=4GB RAM
Hi Yesterday i upgraded an 1 year old System from 4x1GB (32Bit, No Memory-Remap) to 4x2GB (64Bit, Memory-Remap) Today i due to a lucky coincidence i discovered that i have a memory corruption problem. This problem happens only with at least 4GB RAM and Memory-Remap. It happens with any 2 of the 4x2GB RAM-Modules and regardless of slot or dual or single channel configuration. After some trying i found a way to "catch" the error. I wrote a small perl script to fill a tmpfs with 1MB zero-files. Then i MD5 all the files and discard all with the MD5-sum of a 1MB zero-file. Here is what hexdump says about the file-content of the "bad"-file when it is called several times. :/misc/badram> hexdump bad 000 * 00d50a0 84cf 1fff fd0f 00d50b0 * 00d90a0 161f 1fff 43ff 00d90b0 00d90c0 0001 00d90d0 * 010 :/misc/badram> hexdump bad 000 * 00d50a0 84cf 1fff fd0f 00d50b0 * 00d90a0 e59d 1fff 43bf 00d90b0 00d90c0 0001 00d90d0 * 010 :/misc/badram> hexdump bad 000 * 00d50a0 84cf 1fff fd0f 00d50b0 * 00d90a0 f7fb 1fff 43ff 00d90b0 00d90c0 0001 00d90d0 * 010 :/misc/badram> hexdump bad 000 * 00d50a0 84cf 1fff ff03 00d50b0 * 00d90a0 df3b 1fff 43ff 00d90b0 00d90c0 0001 00d90d0 * 010 Strange is that some parts are static and other parts change. Kernel is 2.6.23.11. Kernel is 64Bit/x86-64, Userspace is 32bit. I only need the RAM for a huge ramdisk, so i don't need 64bit userspace. Can anybody help me with this problem?
